I know it gives that description and that cool, but is there a pic or diagram of the screws and sensors that specifically need to be adjusted?

V8, On gnttype there is a pic of sensor locations under resources. The Iac valve is under the uppipe going to the throttle body it is brass colored with a four plug black connector. The screw to adjust the IAC is on the driversside next to the vacuum block on top of the throttle body, it may have a gold cap on it. The TPS sensor is on the passenger side of throttle body and has two screws holding it on it has a black connector on the front of it it is right next to the uppipe.HTH

Just loosen the screws slightly on the TPS, you will see very slight movements will make a big change in voltage. Also remember when you adjust one it affects the other so go back and check the IAC after making TPS adjustments, etc.
